Intake Air Mass Flow

Our AirTrak 628S Thermal Mass Flow Meter was originally designed to work specifically with our BG3 Particulate Partial Flow Sampling System as an extremely fast, accurate, and repeatable engine air intake mass flow meter. In addition, the instrument has proven to be an excellent solution in all engine testing applications.

The meter has an extremely fast 200 millisecond response-time sensor making it ideal for the toughest transient test cycles where flow excursion can approach 10:1 within less than two seconds. Dual-Plate laminar flow profile conditioning elements inside the flow body maintain top performance in heavily constrained piping environments common in engine test cells, where long-straight pipe runs simply do not exist. In addition, the versatile microprocessor-based instrument integrates the functions of easy flow-range adjustment, meter validation and diagnostics in the field, sensor allignment guage for perfect installation, and a rugged probe-mounted NEMA 4X (IP65) housing.
